VBAC After C-Section: Who May Be a Candidate and What Doctors Consider?
VBAC means Vaginal Birth After Caesarean. Some women who have previously had a C-section may be able to have a vaginal birth in a future pregnancy.VBAC is not suitable for everyone. The decision depends on the previous C-section, the current pregnancy and the overall health of the mother and baby.
At Motherly Hospitals, we believe every birth plan should be discussed individually with an obstetrician after reviewing the mother’s previous medical records and current pregnancy.
What Doctors Check Before Considering VBAC
Doctors usually review several important factors before recommending a planned VBAC.
These may include:
- Number of previous C-sections
- Type and location of the previous uterine incision
- Reason for the previous C-section
- Previous vaginal births
- Previous VBAC, if any
- Any complications during the previous delivery
- Recovery after the previous C-section
- Current pregnancy and baby’s position
- Placenta location
- Overall health of the mother
- Any complications in the current pregnancy
The previous operation records can be particularly important because the type of uterine scar affects whether VBAC can be considered.
Previous Uterine Scar Matters
The type of incision made on the uterus is different from the scar visible on the skin.
A previous lower-segment uterine incision is generally considered more suitable for planned VBAC.
A previous classical incision involving the upper part of the uterus is generally a reason not to plan VBAC because of the increased risk of uterine rupture during labour.
Doctors may need to review your previous surgical records before making a decision.
The Reason for the Previous C-Section
The reason for your previous C-section can also be important.
Doctors may consider:
- Baby’s position during the previous pregnancy
- Slow or difficult labour
- Concerns about the baby’s condition
- Previous pregnancy complications
- Other medical reasons for the C-section
A previous C-section for a reason that is not expected to happen again may have different implications from a C-section caused by an ongoing or recurring condition.
Your obstetrician will consider your individual history rather than using one factor alone.
Previous Vaginal Birth Can Be Important
Having had a vaginal birth before can affect the likelihood of a successful VBAC.
This includes:
- A vaginal birth before the previous C-section
- A successful VBAC in the past
According to RCOG guidance, women who have previously given birth vaginally have higher rates of successful VBAC than women without a previous vaginal birth.
Current Pregnancy Also Matters
Even if VBAC was possible in a previous pregnancy, the current pregnancy needs to be assessed separately.
Doctors may check:
- Baby’s position
- Baby’s growth
- Placenta location
- Mother’s blood pressure
- Other pregnancy complications
- Whether labour is expected to be safe
- Whether there is another reason a C-section is recommended
A pregnancy complication that requires a planned C-section may mean VBAC is not appropriate.
When VBAC May Not Be Recommended
VBAC may not be advisable in certain situations, including:
- Previous uterine rupture
- Previous classical C-section scar
- Some complicated uterine scars
- Certain pregnancy conditions where vaginal birth is not recommended
- Some situations involving placenta praevia
- Multiple previous C-sections, depending on individual circumstances
Having two or more previous C-sections does not automatically give the same answer for everyone. Such cases require detailed discussion with a senior obstetrician and assessment of individual risks.
What Happens During a Planned VBAC?
If VBAC is planned, labour is generally managed in a hospital where emergency C-section facilities are available.
During labour, the medical team may:
- Monitor the baby’s heart rate continuously
- Monitor the mother’s condition
- Watch for changes that may indicate a problem with the uterine scar
- Provide appropriate pain-relief options
- Be prepared for an emergency C-section if required
Continuous monitoring is recommended because changes in the baby’s heart rate can sometimes be an early sign of complications involving the previous uterine scar.
Understanding Uterine Rupture
Uterine rupture is a rare but serious complication associated with labour after a previous C-section.
It occurs when the previous uterine scar separates or tears.
Important points include:
- It is uncommon.
- The risk can increase when labour is induced.
- Doctors monitor carefully for warning signs.
- Emergency delivery may be required if there are concerns.
- Having appropriate hospital facilities is important when planning VBAC.
